Answer choices:
A. h = p − 4.2
h = 2p
B. h = 4.2 − p
p = 2h C. h = p − 4.2
p = 2h
D. h = 4.2 − p
h = 2p
h = 2p
B. h = 4.2 − p
p = 2h C. h = p − 4.2
p = 2h
D. h = 4.2 − p
h = 2p

a1/a2 in not equal to b1/b2 i.e. the system of equations will have only one solution. In other words, the graph of the eqations will intersect each other at one point only.
